Replacement Glock OEM barrel
Description
This is the factory GLOCK .40 barrel that comes stock in the Glock model 27. It can be used to convert the 33 to shoot .40 S&W. Using it to convert the 26 to shoot .40 S&W is not safe as it will not fit into the slide properly. Calibers can only be converted down not up.
